SAD-IRON.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed October 15,1906- SerialNo- 339,072.

To all whom it may concern:

Be it known that I, IIARLON M. UNnnnwooi), a citizen of the United States, residing at Bunch, in the county of Davis and State of Iowa, have invented certain new and useful Improvements in Sad-Irons, of which thefollowing is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in self-heating irons, andparticularly to that type known as sad irons.

4 The object of the invention is the improvement of the construction of the body and cover of an iron With this and other objects, in view, the invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a longitudinal, sectional view of an iron constructed in accordance with the present invention. Fig. 2 is a transverse, sectional view of my improved iron.

of the body, with the cover removed. Fig. 4 is an inverted plan view of the cover. Fig. 5 is a detail, fragmentary view of the iron.

Referring to the drawings by numerals 1 designates the bottom of the iron, which is preferably beveled at its ends 2. I bevel one or both of the ends for facilitating the ironing of ruffles of a garment.

Integral with the bottom 1 are sides 3 of the ironbody. Formed in the sides 3, and contiguous to the bottom 1, are alined apertures or ports 4. These apertures 4- are formed entirely around the sides 3 of the body.

At each end of the oval-shaped body, and positioned within the same, is a vertical, reinforcing strip 5, which strip 5 is, preferably, triangular in horizontal section, so as to fit snug into the corner of the body. Integral with each side 3 are vertical, reinforcing ribs 6, 6. These ribs are preferably formed within the body, and greatly increase the strength of the same, because they reinforce the sides thereof, and thereby permit the sides to be formed of thinner metal, although said body is of great strength and durability.

Spaced from the sides 3, and integral with the bottom 1, is a pair of vertical bolts 7, 7. The bolts 7 are threaded upon their upper ends. "hese bolts are of greater height than the sides and extend through apertures 8, 8 when the cover 9 is positioned upon the body. Nuts 10 are threaded upon the extended ends of the bolts 7 for removably securingthe covering in a fixed position upon the body.

The cover or top 9 is provided with a surrounding flange 9 and integral with each side thereof is a pair of vertical, reinforcing ribs 6 which contact with the Fig. 3 is a top plan viewupper ends of the vertical ribs 6 of the body. Each end of the top is reinforced by filling means 1.1, and serve in connection therewith to form a greater head-surface which is preferably transverse blocks, which blocks are secured to the ends of the top and ends of the flange 9.

The transverse, reinforcing blocks 11 for the ends of the oval-shaped cover are, preferably, triangular .in shape. Each triangular, reinforcing block is provided at its outer corners with curved recesses 11, which bear snug against the vertical sides of ribs 6, whereby said recesses 11 and ribs 6 constitute a lock or key for fixedly securing the reinforcing blocks in position at the ends of the oval-shaped cover, against horizontal displacement.

The handle 12 comprises vertical standards 13, 13 and a grip 14. Each standard 13 is provided with a base-piece 1.5, extending at right-angles to the vertical portion of the standard. Any suitable fastening means, as for instance, screws 16, are positioned within the bases 15 of standards 13 and threaded into the top. The handle 14 comprises a bolt 17, upon which is positioned a grip 18, preferably of non-conductive material. By threading nut 19 upon bolt 1.7, the grip is fixedly secured between the standards.

The heating means for the iron comprises a tube or pipe 20 extending through one end of the iron-body and through one of the reinforcing strips 5; the strip 5 carrying the pipe 20, besides reinforcing the body, produces a greater bearing surface or support for said tube 20, thereby increasing the strength of the connection between the pipe and the body. Said tube 20 is preferably coiled at 21., within the iron, and the coiled portion is provided with apertures formed in the bottom thereof. A flexible tube 22 may be connected at one end with tube 20, and at its opposite end with any source for supplying gas to the coiled portion 21 of tube 20. The gas is discharged against the bottom 1 of the iron, and .is ignited, preferably, through the notch or cutout portion 23 formed in the upper edge of one of the sides 3 of the body, Fig. 5. An auxiliary cover 24 is pivoted, at 25, upon one side of the cover or top 9. The auxiliary cover is provided with an enlarged, lower end adapted to fit over the cut-out portion 23 of the iron-body, and its upper end is formed with, preferably, a right-angled extension 26, constituting a grip. Upon the operator grasping the grip 26, and pivoting the auxiliary cover 24 upon its pivot 25, the same may be swung from over the cut-out portion 23, or positioned for covering the same. If it is necessary to supply additional air within the body, the cover may be swung to one side of the cut-out portion for opening the same, and if the operator desires, the pivot, preferably, a screw, may be tightened for holding the slide in the position illustrated in Fig. 5; It is to be noted that this screw constitutes locking means for retaining the auxiliary cover 24 in adjusted positions. Owing to the aperturing oi the coiled portion 21 at its bottom, the flames are directed against the bottom 1 of the body of the iron.

It is desired to heat the upper portidn of the iron as little as possible, and, therefore, I cover the entire inner face of the top and the sides of the iron down to the apertures or ports 4 with an asbestos cover 27. The non-conductive covering terminates short of the bottom 1 on account of not covering the apertures 4. The action of the flame from the coiled portion 21 of the tubing 20, constituting aburner, is entirely against the bottom 1, thereby greatly increasing the heating power of the burner.

What I claim is:

A sad iron comprising a hollow body provided with vertical reinforcing strips at opposite ends which extend from the bottom to the top of the body, a plurality of semicircular ribs formed contiguously on the opposite inner sides of the body, a cover provided with a surrounding; depending flange serving to contact with the upper surface of the body, said cover being also provided with a plurality of ribs which conform to the construction of said ribs of the body and serving to contact therewith, transverse reinforcing blocks arranged Within the opposite ends of the flanged cover and serving to contact with the said strips at the ends of the body, and means for securing said body and cover together, substantially as specified.

In testimony \VllGl'OOf I hereunto aflix my signature in presence of two witnesses.
